Chests for trade in the shop

Question

Many maps have a separate shop faction. Sometimes shopkeepers as me have many customers and it becomes hard to sell anything as anyone can steal a bag of money or gold/items from the dedicated chests. If you open the door, they just halt and banish you. For that reason I suggest adding a new type of chests in the shops where the slots are divided by a line. Such chests can open only 2 persons in the same time not to let others steal from it. They who trade simply place the items/money and confirm the trade by pressing the button, items/money swith the sides and two individuals recieve what they wanted. Also you can place such chests on the spawn/near the shop to let people trade. If the chest is broken - anyone can open and steal.
